我们证明了Kazakov和Migdal最近提出的诱导晶格QCD的晶格模型具有Z[亚[ital N]]规范对称性，在强耦合阶段，导致局部约束，其中仅允许沿链路传播彩色单重态，并且所有非单重态的威尔逊环平均为零。我们认为，如果该模型要给出连续体极限的QCD，它必须有一个相变。我们给出论据来支持这种相变的存在。
We show that a lattice model for induced lattice QCD which was recently proposed by Kazakov and Migdal has a Z[sub [ital N]] gauge symmetry which, in the strong coupling phase, results in a local confinement where only color singlets are allowed to propagate along links and all Wilson loops for nonsinglets average to zero. We argue that if this model is to give QCD in its continuum limit, it must have a phase transition. We give arguments to support the presence of such a phase transition.
